Where are the drain holes on the Avalon's doors?

Detailed introduction is as follows: 1. Drain holes: The Avalon has three drain holes at the bottom of each door, located inside the sealing strip. Two of these drain holes are already open and do not require manual opening, while the third one is blocked with a rubber plug, which can be removed by hand. 2. Timely cleaning: Each door typically has more than two drain holes, usually located at the lower part of the door panel. If these are not cleared, water can accumulate inside the door, leading to rust over time. Additionally, the door contains various components, including the window regulator and wiring for the car audio system, which can be damaged if exposed to water. Since the drain holes on the door are positioned low, they can easily get clogged with mud when driving on muddy roads. Therefore, it is essential to clean the door drain holes promptly. 3. Important notes: There are several other drain holes on the car that require attention, such as the air conditioning drain hole, engine compartment drain hole, sunroof drain hole, trunk drain hole, and fuel tank cap drain hole.

After running this auto repair shop for so many years, I've noticed that the door drain hole locations are pretty similar across Toyota models. The Avalon has four drain holes at the bottom of each door, right where the rubber seal meets the metal door panel. If you squat down and look at the very bottom edge of the door, those half-centimeter wide slits are what you're looking for. Last month, I worked on a flood-damaged car where all four door drains were completely clogged with chewing gum - rainwater accumulated inside the doors and rusted out the window regulators. Remember to use your car key to clear these drain holes whenever you wash your car, especially for vehicles parked under trees. Fallen leaves are the most common culprits for blocking drains, and standing water inside doors will eventually lead to mold growth.

Just yesterday, I cleared the drainage holes on my wife's Avalon, and I remember their locations very clearly. They're right at the very bottom of the door. If you run your fingers along the black dust seal, you'll feel four raised plastic tabs, and the gap in the middle is specifically for drainage. Last week when I washed the car, I noticed the passenger side floor mat was damp, and later found out it was because leaves stuck in the door gap had blocked the drainage hole. I recommend using a thin wire to poke through them every month. The rear door drainage holes are positioned further in, so you'll need to crouch down lower to see them. Oh, and one more thing—don't let the car wash high-pressure water jet spray directly at the drainage holes, as it can easily dislodge the waterproof membrane.

From the perspective of body structure design principles, the arrangement of drainage holes must balance sealing performance and functionality. The Camry's door drainage holes are located in the inner lining interlayer at the bottom of all four doors, utilizing a gravity self-draining design. Specifically positioned at the junction between the door metal panel and interior trim panel, these 5-8cm long slit-shaped structures maintain a safe distance from door anti-collision beams but are prone to mud clogging. When window-down water accumulation in the inner drainage channel exceeds threshold, fluid discharges through these preset openings. Routine maintenance involves checking drainage sounds: slowly pour 200ml water into window gaps - normal drainage should produce audible water flow within 3 seconds.
